Sen. Richard Lugar
(R-Ind.), who will have to fend off state Treasurer Richard Mourdock
(R), who is running to his right in the GOP primary, received a 70 percent rating -- up seven points from his 63 percent lifetime rating.
Unlike Hatch, Lugar has shown more resistance to assuaging concerns from the Tea Party. Club President Chris Chocola recently said
"we think it would be probably best" if Lugar "would retire at this point."
Also notable in the ratings is the rise in score for several Republican Senate candidates who are Members of the House. Rep. Dean Heller
(R-Nev.), who will soon be appointed to the Senate but had already jumped into the 2012 race, has a 2010 score of 94 percent versus a lifetime score of 83 percent. Rep. Denny Rehberg
(R-Mont.) has a 2010 score of 84 percent compared to 61 percent overall. And Shelley Moore Capito
(R-W.Va.), a potential 2012 Senate candidate, scored a 74 percent rating for 2010 and a 50 percent lifetime score.
The Club for Growth is an organization focused on fiscal conservatism and limited government. So far this cycle, their political action committee has only endorsed Rep. Jeff Flake
(R-Ariz.), who is running for retiring-Sen. Jon Kyl
's (R) seat. Flake boasts a 100 percent 2010 score as well as a 100 percent lifetime score.
The Club rating was based on
legislative actions that impact the organization's policy goals related to economic growth.
